We have four cars in use in our household. They are petrol trucks with a standard battery capacity of about 60-100 Ah. At the moment we still have an ancient charger of Einhell, which can be switched between 6 and 12 volts and with a completely unloaded 12 V car battery a charging current of about 0.5 A. For a maintenance charge over the winter or a complete charge over several days this is fine, but I am now looking for a charging charge. advises, with which I can recharge the batteries well within one day. It would also not be bad if you could start the car with a completely discharged battery within 1-2 hours (with connected charger). Do I lie with a charger which provides a current of approx. 8-15 A thus correct? Are there specific recommendations which brands/models are especially recommended?
